The Verband Privater Bauherren (VPB) is a non-profit membership association with over 40 years of experience, supporting private project owners from drafting contracts through to acceptance of the building work. The VPB is recognised by the Federal Ministry of Justice (BMJ) as an independent consumer organisation.4 Cleverbauen24 is a digital service specialising in targeted reviews of individual construction quotes. Both approaches address the same problem in different ways: protecting project owners against excessive prices and contractual risks.
Key points at a glance
- VPB membership costs 18 €/month plus consultancy fees of 120–180 €/h — worthwhile for construction monitoring over several months
- An individual quote review typically costs 350–600 € with the VPB; Cleverbauen24 starts at 79 € with results in 24h to 4 working days
- VPB membership is particularly worthwhile for new builds or extensive renovations with regular site monitoring
What does the VPB offer?
The VPB maintains around 80 regional offices across Germany, with technical advisers, architects and surveyors.1 Advice is provided personally and on site, which is a clear advantage for complex construction projects in particular.
The VPB's services essentially include:
- Construction monitoring: Regular site inspections by a technical adviser who checks construction progress and records defects. KfW funds independent construction monitoring through its energy-efficient construction and renovation programmes, covering up to 50 per cent of the cost (max. 5.000 euros).5
- Contract review: Reviewing construction contracts and quotes for unfavourable clauses, missing services and pricing risks.
- Acceptance of building work: Support during formal acceptance, recording defects and securing evidence.
- Mould investigation: Analysis of moisture damage and findings of harmful substances in existing buildings.
- Dispute support: Assistance with disputes involving contractors or general contractors, including expert reports.
The VPB's pricing consists of two components: a membership fee of around 18 euros per month (216 euros per year) and an hourly rate of 120 to 180 euros for the actual advisory service.1 An individual quote review usually takes one to three hours of advisory time, depending on its scope and the region.
Note: VPB membership is particularly worthwhile if you need several services over an extended period, for example for a new build requiring construction monitoring, acceptance support and subsequent monitoring during the defects liability period.
What does Cleverbauen24 offer?
Cleverbauen24 specialises in digitally reviewing construction quotes. The quote is uploaded as a PDF and assessed within 3 to 4 working days (Basic) or 24 hours (Express) through a combination of AI-assisted analysis and manual expert review.
The review covers seven categories:
- Risks of variations and additional charges
- Technical risks and missing services
- Transparency of work and services
- Liability and defects liability
- Price plausibility against regional benchmarks
- Quantity and calculation checks
- Contractor and company quality
The result is a structured review report with specific recommended actions for each issue. No membership or site appointment is required. Prices and service scope are transparent and available before ordering. Find out more in our guide Reviewing a construction quote.
Cost comparison
The cost difference between VPB advice and a digital quote review is considerable. For a single quote review, VPB members need to budget for one to two hours of advisory time in addition to their membership fee.
Specifically: with a membership fee of 18 euros per month and an hourly rate of 175 euros, a one-hour quote review already costs around 193 euros, rising to around 368 eurosfor two hours. If a site inspection is needed to assess the quote in detail, the total quickly reaches 400 to 600 euros.
| Provider | Cost | Turnaround |
|---|---|---|
| Independent surveyor | 360 to 714 euros | 2 to 4 weeks |
| Consumer advice centre | 180 to 370 euros | 1 to 3 weeks |
| VPB | 175 euros+/hour | by arrangement |
| Cleverbauen24 | from 79 euros | 3–4 days (Basic) / 24 hours (Express) |
For construction projects with a contract value of 20.000 euros or more, a professional review can be financially worthwhile in any case, as the review fee generally represents a fraction of the potential savings. Our guide provides a detailed assessment of when each option is worthwhile Comparing contractors' quotes.

When is the VPB worthwhile?
The VPB is the right choice if you are planning a complex construction project that requires more than a quote review. Typical situations include:
- New build with a general contractor: When a single company delivers the entire building, ongoing construction monitoring helps identify defects early. According to the Bauherren-Schutzbund (BSB), turnkey contracts with general contractors contain the most unfavourable clauses on average.6
- Long-term construction monitoring: If you need advice repeatedly over several months, membership can be more economical than numerous individual consultations.
- Acceptance support: A technical adviser attending acceptance of the building work can spot hidden defects that non-specialists easily overlook. TÜV Süd reports that professionally supported acceptance inspections document twice as many defects on average as inspections without an expert.7
- Dispute with the contractor: If an out-of-court resolution or expert report is needed, the VPB has the relevant network.
When is an online review sufficient?
In many cases, a digital quote review is sufficient and more cost-effective. This particularly applies when:
- Assessing an individual quote: You have received one or more quotes for a specific project and want to know whether the prices and services are reasonable.
- Renovation involving a single trade: For clearly defined projects such as bathroom refurbishment, external wall insulation or painting, a quote review is generally sufficient. More on typical renovation costs in our guide Reviewing a construction quote.
- Time pressure: If you need an assessment quickly, for example because the contractor has set a short acceptance deadline, the Express review provides a result within 24 hours.
- No subscription wanted: Anyone who does not want to pay an ongoing membership fee is better served by a one-off review.
Combining both approaches
This does not have to be an either-or decision. For extensive construction projects, a sensible combination might look like this: first have the quote reviewed digitally to obtain a quick initial assessment and identify obvious problems. If this reveals serious shortcomings, or the project requires ongoing monitoring, bring in the VPB for on-site advice.
This approach saves time and money: the digital review provides a sound basis for discussion with the VPB adviser, who can then address the identified risks directly instead of analysing the entire quote from scratch.

Frequently asked questions
How much does VPB advice for project owners cost?
VPB membership costs around 18 euros per month. There is also an hourly rate of 120 to 180 euros for the actual advisory service. A quote review involving one to two hours of advisory time therefore costs around 300 to 500 euros in total, excluding travel costs for site appointments. Exact terms vary by regional office.1
Do I need VPB membership for a quote review?
No. You can have a construction quote professionally reviewed without VPB membership, for example through a consumer advice centre, an independent surveyor or a digital service such as Cleverbauen24. Membership only makes sense if you want to use several advisory services over a longer period.
What is the difference between the VPB and an online quote review?
The VPB provides personal, on-site advice from architects and surveyors, covering the entire construction process. A digital quote review focuses on the pricing and services in a specific quote, is faster and less expensive, but does not replace ongoing construction monitoring or acceptance support.
Is VPB membership worthwhile for a renovation?
That depends on the scope of the renovation. A digital quote review is generally sufficient for a defined project such as bathroom refurbishment or external wall insulation. For a comprehensive refurbishment or conversion involving several trades and a value of 100.000 euros or more, VPB membership with ongoing construction monitoring can make sense. According to Destatis, around 130 billion euros were spent on work to existing residential buildings in Germany in 2024.8
Can I combine the VPB with an online review?
Yes, this is possible and sensible in certain situations. A digital quote review provides a quick initial assessment and identifies specific issues that the VPB adviser can then explore in a personal consultation. This saves time during the site appointment and enables more targeted questions.

Comments
I used VPB for my new build and was very happy. The construction supervision was worth every cent.
Roughly how much does VPB membership cost per year?
VPB membership costs around 80–120 euros per year depending on the regional association, with advisory services on top (hourly rates around 80–150 euros). Comprehensive construction support can quickly total 1,500–3,000 euros. That is money well spent if you are building — rather disproportionate for a one-off quote review.
The article makes it clear: VPB for new-build supervision, a specialist service for quote reviews. That makes sense.
Finally, a direct comparison instead of nothing but glowing praise. Very helpful.
